"Indeed, the real seat of all superiority, even of manners, must be placed in the mind: dignified sentiments, superior courage, accompanied with genuine and universal courtesy, are always necessary to constitute the real gentleman; and where these are wanting, it is the greatest absurdity to think they can be supplied by affected tones of voice, particular grimaces, or extravagant and unnatural modes of dress; which, far from becoming the real test of gentility, have in general no other origin than the caprice of barbers, taylors, actors, opera-dancers, milliners, fidlers, and French servants of both sexes."
— Day, Thomas (1748-1789)
